UNHT YATES DAVID L. HOOVER, OF HUNTSVILLE, ALABAMA.

ADVERTISING CLOCK.

Application filed January 28, 1922.

T 0 all whom it may concern:

Be it known that I, DAVID L. HOOVER, a citizen of the United States, residing at Huntsville, in the county of Madison and State of Alabama, have invented certain new and useful Improvements in an Advertising Clock, of which the following is a specification.

The present invention relates to an advertising clock and has for its principal object to provide a simple and efiicient advertising mechanism which may be situated in a clock casing for displaying a changeable s1 11.

With the above and numerous other objects in view which will appear as the description progresses, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be herein after more fully described and hereinafter claimed.

In the drawing Figure 1 is a front elevation of the clock embodying'my invention,

Figure 2 is a section taken therethrough,

Figure 3 is a detailed section taken at right angles to Figure 2 through the lower portion of the clock showing the changeable sign mechanism,

Figure 4: is a detailed view showing the manner in which the sign is attached to the chain, and

Figure 5 is a detailed section taken on the line 5-5 of Figure 3 looking in the direction of the arrow.

Referring to the drawing in detail it will be seen that l, designates a casing which is provided with a clock 2 of any preferred construction mounted in the upper end thereof. In the lower end of the casing there is mounted a changeable sign mechanism including a pair of spaced shafts 3 and 4 suitably journalled in the casing as at 5. Each of the shafts 3 and 4 are provided with a pair of sprocket wheels 6 adja cent each end over which are trained the chains 7 for receiving a plurality of signs one of which is shown at 8. This sign 9 is provided with spring clips 9 which engage the links 10 of the chain as disclosed to advantage in Figure 4 of the drawing. The shaft 4 at the bottom of the casing is pro- Serial No. 532,419.

vid ed with a worm gear 11 keyed thereto which is in mesh with a worm 12 mounted on the shaft 13 which is journalled in a bracket 14 of U-shaped construction. A lever 15 is mounted on the shaft 13 so as to engage and rotate the same in one direction through a spring pressed pawl 17 engaging suitable teeth provided on the shaft 13. By moving the lever 15 it will be readily understood that a sign such as 8 may be brought before an opening in the housing 1. These signs may be readily changed at will by the operation .of the lever 15.

A gong 21 is situated in the casing l and is struck by a hammer 22 actuated by the clock mechanism 2 in any suitable manner at such desired intervals so as to attract attention both to the clock and to the sign. Suitable illuminating means 23 is mounted in the casing so as to illuminate both the face of the clock 2 and the sign visible through the opening'20.

It is of course understood that the clock casing is to be furnished with the usual means of opening whereby the clock may be wound and the hands adjusted and this same means of opening to act as means of access to the present invention.

Having thus described my invention what I claim as new is An advertising device of the class described including in combination a casing, a changeable sign mounted in the casing, a pair of spaced shafts journalled in said cas ing, a pair of endless members trained over the shafts, a sign carried on the chains, a worm gear carried on one of the shafts, a third shaft mounted in the casing and provided with a worm meshing with the worm gear, a lever having a spring pressed pawl, ratchet means disposed between the lever and the third shaft for actuation thereon in one direction, said lever moving in a plane parallel with the plane in which the pair of spaced shafts is situated.

In testimony whereof I aiiix my signature in presence of two witnesses.

DAVID L. HOOVER.
